S6: Personal Protective Equipment Flashcards
Def of PPE
- PPE is equipment designed to protect workers from serious workplace injuries or illnesses resulting from contact with chemical, radiological, physical, electrical, mechanical, or other workplace hazards.
PPE is used as the ….. in the hierarchy of control
last step
Requirements of PPE
Limitations of PPE
- Safety Hazards
- Physiological/Psychological stressors
- Management Requirements
Limitations of PPE
- Safety Hazards
- Restricted movement due to weight
- Restricted vision due to visual field limitations
- Difficulty communicating due to face protection
Limitations of PPE
- Physiological/Psychological stressors
- Psychological stress resulting from confining nature of full suits
- Heat stress and risk of dehydration
- The highest levels of PPE generally cannot be worn continuously for more than 30 minutes
Limitations of PPE
- Managment Requirments
- Need for a management program that ensures effective use of PPE
- Facial hair interferes with proper fit of masks
- Improper use, penetration/tears are potentially hazardous
When PPE is provided it is required that all employees receive the correct information, instructions and training on its use and show how the equipment should be maintained, cleaned and disposed of.
..
- An effective system of maintenance of PPE is essential to make sure the equipment continues to provide the degree of protection for which it is designed for.
..
- Maintenance may include cleaning, examination, replacement, repair and testing.
..
- Storage of PPE should be adequate to protect the PPE from contamination, loss, damage or sunlight

Examples of Eye and Face Protective Equipment
Indications of use of Eye and Face Protective Equipment
Examples of Head Protective Equipment
- Industrial safety helmets (hard hats)
- Industrial scalp protectors (bump caps)
- Caps/hair nets
Industrial safety helmets (hard hats)
- designed to protect against materials from a height or swinging objects
Industrial scalp protectors (bump caps)
- designed to protect from knocking
against stationary objects
Caps/hair nets
protect against entanglement
Tasks where head protection may be required include ….
Requirments of Head Protective Equipment
- Resist penetration by sharp objects.
- Absorb shock.
- To be water-resistant and slow burning
Types of Foot and Leg Protective Equipment
- Leggings
- Toe guards
- Combination foot and shin guards
- Safety shoes
- Electrical hazard, safety-toe shoes
Safety shoes
Have impact-resistant toes and heat-resistant soles that protect the feet against hot work surfaces common in roofing, paving and hot metal industries.
Electrical hazard, safety-toe shoes
are non-conductive and will prevent the wearer’s feet from completing an electrical circuit to the ground
Indications of Foot and Leg Protective Equipment
Types of protective gloves
What are Rubber gloves Made of?
natural (latex), butyl, neoprene, and fluorocarbon (viton).
What are Plastic gloves Made of?
polyvinyl chloride (PVC), polyvinyl alcohol and polyethylene.
Indications of Hand and Arm Protective Equipment
The best surgical gloves used instead of latex gloves, in case of latex allergy are made of …..
nitrile
Types of Body Protective Equipment
Include laboratory coats, coveralls, vests, jackets, aprons, surgical gowns and full body suits
Body Protective Equipment are made of ……
Indications of Body Protective Equipment
- Temperature extremes.
- Hot splashes from molten metals.
- Potential impact from tools, machinery and materials.
- Hazardous chemicals.
Indications of Hearing Protective Equipment
Exposure to hazardous level of noise (> 85 dB / 8 hr).
Types of Hearing Protective Equipment
- Earplugs
- Earmuffs
What is Earplugs made of?
Made of waxed cotton, foam & silicone rubber.
Effect of Earplugs
They decrease noise level 15 dB by decreasing air conduction
Effect of Earmuffs
Decrease both air and bone conduction, so reduce noise level 35 dB.
Respirators may be ……
- Tight or Loose Fitting
- Air-Purifying or Atmosphere-Supplying
What is a Respirator?
Is a protective device that covers the nose and mouth or the entire face or head to guard the wearer against hazardous atmospheres.
Tight-fitting Respirators
That is, half masks, which cover the mouth and nose and full face pieces that cover the face from the hairline to below the chin.
Loose-fitting Respirators
Such as hoods or helmets that cover the head completely.
Air-purifying respirators
Which use filters or sorbents to remove harmful substances from the air.
Atmosphere-supplying respitrators
Provide clean, breathable air from an uncontaminated source.
Indications of Respiratory Protective Equipment
1) Insufficient oxygen.
2) Harmful dust, fogs, smokes, mists, fumes & gases.
3) Toxic substances present in the workplace.
Face masks rely on a good seal against the face, if there are gaps in the face mask then contaminated air, dust, gases and vapors may be breathed into the
lungs
..
For this reason it is very important your mask fits properly and is used correctly every time you use it.
..
so employees need to do face fit testing of RPE.
..
There are two forms of face fit testing
- Qualitative fit testing
- Quantitative fit testing
Qualitative fit testing
is suitable for disposable filter face pieces and half masks
Quantitative fit testing
is recommended for full face masks.
